patch labels in CG manual

[Federico Bruni]

Hi

I have a few questions about the section "Patch label" in:
http://lilypond.org/doc/v2.19/Documentation/contributor/issue-classification

> Patch-new: the patch has not been checked for “obvious” mistakes. 
> When in doubt, use this tag.
> Patch-review: the patch has no “obvious” mistakes (as checked by 
> the Patch Meister), and is ready for review from main developers.
>
> Developers with git push ability can use this category, skipping over 
> patch-new.


Recently I've followed this guide and used Patch-review immediately 
after uploading the patch, because I thought this would have saved 
manual work to James.

But I've just learned from Phil that if I skip immediately to 
Patch-review the tests won't run¹. This is confirmed by this chapter:
http://lilypond.org/doc/v2.19/Documentation/contributor/the-patch-review-cycle

I can't remember if Patchy still does (after the move to 
Allura/Sourceforge) what's described there.
Anyway, I would add a link to the-patch-review-cycle from 
issue-classification#patch-label section and I would change the above 
paragraph to say that automatic tests are run when an issue is set to 
Patch-new.
